The problem that I see with the measurement device is that softness is actually best represented as a curve with depth of deformity on the y-axis and resistance on the x-axis. As someone above pointed out tpe is homogeneous and can start off soft but gather a lot of resistance fast on depth deformation. Unlike the human breast which has very little pushback at most any depth except the very end up against bone.

Great thanks!

Please feel free to send TPE material samples to Indigo, and you will get a softness rating within a couple of days.

This method to measure TPE softness requires lab equiment; it can not be done at home by yourself.

Do you have ratings for the softer formulas? E.g., supposedly Jinsan brands are available in:

Normal (75)
Extra soft (??)
Ultra soft (??)

I've read that Jinsan "Ultra soft" has poor durability, but it would be interesting to know the rating for comparison.

As far as I know this is not a new material (which would require a technology to blend different TPE materials), but a customization of hollow breasts (more or less air pressure inside the breast cavity).

Indigo's softness ratings does measure chemical characteristics of TPE, not what's physically or mechanically below the material (e.g. air pressure, foam core, metal skeleton).

Is there a rating on the ORdoll "new softness material"?

ORdoll wrote:Yes - I send him this video

Thank you Mr Harem for putting it online.

I aim for the most natural feeling breasts of all dolls. This is a new softness material tested extensively for the G cup but not at present for the H cup.

Kind Regards

The Doll Forever rating is 90, so yes.

But wait, to be precise, 'Doll Forever [2016/2017]' is 90. As far as I know, this blend is not used anymore. The current TPE blend 'Doll Forever [2017 ss.]' is firmer and has not yet been rated. The current D4E TPE blend will be probably in the EVO range (but also has other changed attributes, like enhanced tearing resistance).

Brilliant - Sandro to the fore very much so here. Congratulations.

These measurements accord with my subjective experience.

I don't think JY hardness has changed between old and new.

Best wishes

Harem

Yep. A few months ago I bought a Shore-OO durometer and tested my OR and D4E dolls:

Thanks Sandro for posting this.

Does this mean Indigo is better?

Yea, that threw me off as well. Problem with using the durometer scale is that granularity is limited. The differences between WM and DH168 would likely be measured in tenths or hundredths. I don't believe this type of precision is an affordable option.

That would make the most sense, Dullahan. Maybe it’s coincidence, but the numbers listed here so far are within the range of the A scale used for softer TPE hardness. Maybe that’s what they’re using.

To Anung’s point, adding the flexural modulus stiffness test would help determine durability of the TPE since it would approximate ability of being stretched around bent knees and elbows and being stretched when a doll’s arms are raised or legs spread.

Edit: I just thought I’d this. Using shore hardness, the lower the reading the softer the material. That’s the opposite of what was stated in the original post.

Anung

Yeah, this is key. Hopefully they’re not getting the softness at the cost of resilience.
